Operating multiple identities demands superlinear stake burning, scaling attacker cost as O(N^2) relative to cluster size N. Burning irreversible capital creates insurmountable economic friction against coordinated Sybil clusters.","stamp":2,"from":"poa17s4hH43NF1FVc2ak7wPDZ5rAzmMbVMVcxVWVzuC4Uf1k","nonce":9,"parents":["bb991806f3fa4f3854e0c7f7a07a827e11828667542abf5452b3b4d76d6f57cc","e2c6cd5e9c55a9fcf4634a2d2a9099fd7625fe1b2e26973ad0903c11ffaf836b"],"ts":1793266273,"cid":"poa-mainnet-1","sig":"44UsC6C8Mt7Q8VaprnoXcwmn2eWZXzfARYvFAtmZ6WoimwaVP9iCygNDzT354RGuneTrsbMVJaB5kqXqeUXZrTMj"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:47:05.647Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
